Subject: [PATCH 5.19 091/365] dt-bindings: pinctrl: mt8192: Add drive-strength-microamp
From: NĂcolas F. R. A. Prado <nfraprado@...labora.com>
commit b52e695324bb44728053a414f17d25a5959ecb9d upstream.
Commit e5fabbe43f3f ("pinctrl: mediatek: paris: Support generic
PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using
drive-strength-microamp instead of mediatek,drive-strength-adv.
Since there aren't any users of mediatek,drive-strength-adv on mt8192
yet, remove this property and add drive-strength-microamp in its place,
which has a clearer meaning.
Fixes: 4ac68333ff6d ("dt-bindings: pinctrl: mt8192: Add mediatek,drive-strength-adv property")

- Describe the specific driving setup property.
- For I2C pins, the existing generic driving setup can only support
- 2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
- can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
- driving setup, the existing generic setup will be disabled.
- The specific driving setup is controlled by E1E0EN.
- When E1=0/E0=0, the strength is 0.125mA.
- When E1=0/E0=1, the strength is 0.25mA.
- When E1=1/E0=0, the strength is 0.5mA.
- When E1=1/E0=1, the strength is 1mA.
- EN is used to enable or disable the specific driving setup.
- Valid arguments are described as below:
- 0: (E1, E0, EN) = (0, 0, 0)
- 1: (E1, E0, EN) = (0, 0, 1)
- 2: (E1, E0, EN) = (0, 1, 0)
- 3: (E1, E0, EN) = (0, 1, 1)
- 4: (E1, E0, EN) = (1, 0, 0)
- 5: (E1, E0, EN) = (1, 0, 1)
- 6: (E1, E0, EN) = (1, 1, 0)
- 7: (E1, E0, EN) = (1, 1, 1)
- So the valid arguments are from 0 to 7.
